Documentation: DT: Fix a typo in the filename "lantiq,<chip>-pinumx.txt"
To fix it, use the chance to rename according the compatible string, which is "lantiq,pinctrl-falcon" and "lantiq,pinctrl-xway" Signed-off-by: Thomas Langer <thomas.langer@lantiq.com> Cc: John Crispin <blogic@openwrt.org> Signed-off-by: Rob Herring <robh@kernel.org>

-Lantiq XWAY pinmux controller
-
-Required properties:
-- compatible: "lantiq,pinctrl-xway" or "lantiq,pinctrl-xr9"
-- reg: Should contain the physical address and length of the gpio/pinmux
- register range
-
-Please refer to pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices, including the meaning of the
-phrase "pin configuration node".
-
-Lantiq's pin configuration nodes act as a container for an arbitrary number of
-subnodes. Each of these subnodes represents some desired configuration for a
-pin, a group, or a list of pins or groups. This configuration can include the
-mux function to select on those group(s), and two pin configuration parameters:
-pull-up and open-drain
-
-The name of each subnode is not important as long as it is unique; all subnodes
-should be enumerated and processed purely based on their content.
-
-Each subnode only affects those parameters that are explicitly listed. In
-other words, a subnode that lists a mux function but no pin configuration
-parameters implies no information about any pin configuration parameters.
-Similarly, a pin subnode that describes a pullup parameter implies no
-information about e.g. the mux function.
-
-We support 2 types of nodes.
-
-Definition of mux function groups:
-
-Required subnode-properties:
-- lantiq,groups : An array of strings. Each string contains the name of a group.
- Valid values for these names are listed below.
-- lantiq,function: A string containing the name of the function to mux to the
- group. Valid values for function names are listed below.
-
-Valid values for group and function names:
-
- mux groups:
- exin0, exin1, exin2, jtag, ebu a23, ebu a24, ebu a25, ebu clk, ebu cs1,
- ebu wait, nand ale, nand cs1, nand cle, spi, spi_cs1, spi_cs2, spi_cs3,
- spi_cs4, spi_cs5, spi_cs6, asc0, asc0 cts rts, stp, nmi , gpt1, gpt2,
- gpt3, clkout0, clkout1, clkout2, clkout3, gnt1, gnt2, gnt3, req1, req2,
- req3
-
- additional mux groups (XR9 only):
- mdio, nand rdy, nand rd, exin3, exin4, gnt4, req4
-
- functions:
- spi, asc, cgu, jtag, exin, stp, gpt, nmi, pci, ebu, mdio
-
-
-
-Definition of pin configurations:
-
-Required subnode-properties:
-- lantiq,pins : An array of strings. Each string contains the name of a pin.
- Valid values for these names are listed below.
-
-Optional subnode-properties:
-- lantiq,pull: Integer, representing the pull-down/up to apply to the pin.
- 0: none, 1: down, 2: up.
-- lantiq,open-drain: Boolean, enables open-drain on the defined pin.
-
-Valid values for XWAY pin names:
- Pinconf pins can be referenced via the names io0-io31.
-
-Valid values for XR9 pin names:
- Pinconf pins can be referenced via the names io0-io55.
-
-Example:
- gpio: pinmux@E100B10 {
- compatible = "lantiq,pinctrl-xway";
- pinctrl-names = "default";
- pinctrl-0 = <&state_default>;
-
- #gpio-cells = <2>;
- gpio-controller;
- reg = <0xE100B10 0xA0>;
-
- state_default: pinmux {
- stp {
- lantiq,groups = "stp";
- lantiq,function = "stp";
- };
- pci {
- lantiq,groups = "gnt1";
- lantiq,function = "pci";
- };
- conf_out {
- lantiq,pins = "io4", "io5", "io6"; /* stp */
- lantiq,open-drain;
- lantiq,pull = <0>;
- };
- };
- };
